The purpose of this study is to analyze the work value factors regarded as important by the culinary-related graduates in their 20s, and also to analyze the effects of work value factors on the life satisfaction. To achieve this purpose, this study analyzed the data of 155 graduates from departments including 'culinary arts', 'foodservice', and 'confectionery' among the college graduates in their 20s who participated in GOMS 2018. The results of analysis are as follows. First, the new generation majors in culinary arts showed the high importance of their aptitude and interest, employment stability, earned income. Second, in relation to the major field, the male graduates majored in culinary arts more highly perceived the importance than the female graduates majored in culinary arts. On the other hand, regarding the social reputation of job and work duty, the female graduates majored in culinary arts more highly perceived the importance than the male graduates majored in culinary arts. Third, the developmental value factor of work value had positive effects on the life satisfaction. Thus, the career-related staffs or professors of college should provide the career guidance by considering gender when the majors in culinary arts transit to the labor market after graduation.

A new Valley-fill circuit for improving PF(power factor) is proposed in this paper. The proposed topology combines Valley-fill rectifier and an additional inductor for boosting. In the proposed circuit, a shapc of input current is related to the PWM duty cycle. The boosting inductor makes improve PF by the electric charge transfer action. The operation principle and the shape of input current arc analyzed as applied the boosting inductor. The optimum value of boosting inductor is determined. A 100W single-stage converter has been designed and tested. Experimental results are presented to verify the validity of the proposed converter.

Maximum Power Point Tracker (MPPT) is the big issue in generating power based on Wind Energy Conversion System. In case of unknown turbine characteristic, it is useful to implement MPPT based on fuzzy logic control. This kind of control is able to find the value of duty cycle to meet maximum power point at particular wind speed. There are many methods to develop MPPT based fuzzy logic controls. In this paper, two of the methods are compared both at low and high fluctuating wind speed.

In this paper, Flyback type DC/DC Switching Converter was designed, analyzed and fabricated. Worst Case Analysis(WCA) was peformed with Mathcad program and presents circuit simulation results for the in-rush current limit circuit. The value of the maximum OFF voltage stress is 131.84V, it is less than device specification(200V). The switching frequency(nominal case) and duty cycle at the wont case analysis are 75KHz and 34.62%, respectively. The maximum in-rush current presents 0.5A Those results show a possibility for use in space

People who cook often say "cooking is art" or "cooks are the same as doctors". But matter how hard they way repeat these speaking, if they are not permitted socially, that becomes a useless thing. To sublime cooking into the art and cook like doctor′s prescription, culinary duty must be peformed by craftsman spirit and soul to endow artistic value. And culinary course is carried out by virture of scientic basis like doctor′s prescription.

The free trade zone would be evaluated at the point of granting exceptions of lease and disposal of land and manufactory, the organic relationship of the Manufacture and distribution, the reduction of rental value for foreign investment company and tax refund or exemption for customs duty that can be able to extend and draw new foreign investment enterprises. But despite of these, Free Trade zone, taking it in all its bearings, I considered its institutional problems and tried to find betterment of this.

The objective of this research is to find the influence of professionalism on the organizational performance, where 437 people of physical therapist, radiological-technologist, medical laboratory technologist and occupational therapist working for 35 medical service utilizations were included. The professionalism employed for medical technicians has shown significant difference on the duty performance, job meaning, appropriate salary and job autonomy with sex and ages among the value variables for jobs, and the influence of duty has shown the significant difference only on the ages. Second, the appropriate salary among the variable values for jobs has the most significant influence on the systemicity and the affections to jobs of measurable values. Third, it has shown that the higher years at work among the duty special quality have strong affection to workplace. Fourth, from the result of occupational category, the professional values affecting the organizational performance of medical technicians have difference on the type of medical technicians.

The purpose of this study is to evaluate representativeness of fuel-based emission factors. Twelve light-duty diesel vehicles which meet Euro-3 to 5 legislative emission limits were selected for emission tests. Second-by-second modal emission rates of vehicles were measured on a standard laboratory chassis dynamometer system. An off-cycle driving cycle was developed as a representative Korean real-world on-road driving cycle. Fuel-based emission factors were developed for short trip segments that involved in the selected driving cycle. Each segment was defined to have unit travel distance, which is 1 km, and characterized by its average speed and Relative Positive Acceleration (RPA). Fuel-based $NO_x$ emission factors demonstrate relatively good representativeness in terms of vehicle operation conditions. $NO_x$ emission factors are estimated to be within ${\pm}20%$ of area-wide emission factor under more than 40% of total driving situations. This result implies that the fuel-based $NO_x$ emission factor could be practically implemented into the on-road emission management strategies, such as a remote sensing device (RSD). High emitting vehicles as well as high emitting operating conditions heavily affect on the mean values and distributions of CO and THC emission factors. Few high emitting conditions are pulling up the mean value and biasing the distributions, which weaken representativeness of fuel-based CO and THC emission factors.

In spite of many advantages of Meteor Burst Communications(MBC) on its transmission channel, the fact that its duty rate is less than 10 percents is a considerable deficiency of MBC. To overcome with this deficiency without paying large cost, we use a direct sequence(DS) simple reception system. This method doesn't need to add the components for acquisition or tracking the signal so that it keeps the cost efficiency of the MBC. But it has a disadvantage that its duty rate shows a large decline by noise. For this problem we adopt the proposed system applying a transversal filter circuit. The improvement by this method is more significant when the received signal is weak Simulation results show as t1 is 100ms, then the burst length would be increased by 35% when the initial value of the received signal power increases by 3 dB, t2 is 135ms. If the power increases by 6dB the burst length would be 170ms thus increased by 70%, which shows a great enhancement. Suppose now that t1 is 50ms and the power is increased by 3dB, then t2 would be increased by 70% to 85ms, and increasing the power by 6dB it would be increased by 130% to 115ms.

The activated partial thromboplastin time (APTT) is used primarily to evaluate coagulation abnormalities in the intrinsic pathway. The proper specimen is very important factor for precise results of blood coagulation analysis. The objective of this study was to get to the conclusion of whether to analyze again and to collect blood sample over again when APTT result shows below the reference value. We evaluated 126 samples showing a value below 20.0 sec at ATPT result, which consist of 48 males and 78 females candidates during night duty from March 2012 to December 2012. Average comparisons of APTT result between first and retested analysis among study subjects were significantly different in male samples. APTT results comparison of recollected subjects among clotted samples were also significantly different with both sexes (p<0.000). We suggest that we should carefully check the samples to get accurate results and collect samples again in case of only obtaining improper samples; even though the APTT result show below reference value.
